[BUG] Deleted bots not being deleted properly

[ptrckbp]

Describe the bug
If I delete a bot, then create a new one with the same id, the flows of the old one come included in the new bot.

To Reproduce
Steps to reproduce the behavior:

1. Create a bot with a certain id with the empty template
2. Rename the node
3. Delete the bot
4. Recreate a bot with the same id
5. Go back to the flow page, and see the renamed node

Expected behavior
The node should not be renamed in the new bot. Deleting a bot should delete all information about it.

Environment (please complete the following information):

• OS: macOS
• Browser Chrome
• Browser Version Version 92.0.4515.131 (Official Build) (x86_64)
• Botpress Version 12.25.0
• NodeJS 12.13.0

Additional context
If you use something like test or test-2 or whatever-you-are-working-on-2 as an id, this problem will be very frustrating. My first thought was that export was broken! Thankfully I could demonstrate that it was not by restarting the Botpress server and seeing this problem go away. :)
